Node metrics
Themetric values of GET /nodes/metrics. Each row is one figure for one group or node, one section and one night.
member_count
Members. Active memberships of young people. A young person in two groups counts once in each.
- Counts each active membership whose young person is not archived.
- A young person in two groups counts once in each group, so a total above those groups counts them twice.
- To count each young person once, read
young_people_count.
unassigned. The section rows sum to all exactly.
How fresh: Built each night. A group that stops sharing, or moves to another district, leaves the totals above it at the next build, within 24 hours.
waiting_count
Waiting list. Open waiting list entries.
- An entry counts while it is received, contacted or offered. Entries that have joined, withdrawn or been removed do not.
- A child on two groups’ waiting lists counts once on each.
unassigned. The section rows sum to all exactly.
How fresh: Built each night. A group that stops sharing, or moves to another district, leaves the totals above it at the next build, within 24 hours.
net_growth_12m
Net growth (12 months). Memberships that started minus memberships that ended, over the 12 calendar months (UTC) up to and including the month the figure was built.
- A membership started when its join date falls in the window, whether or not it has ended since.
- A membership ended when it was archived in the window. An archive from before archive dates were recorded is dated by the last change to the young person’s record.
- So a young person who joined and left inside the window counts as one that started and one that ended: no change.
- A negative value means more memberships ended than started.
all only. The section a young person joined is not kept, so a split by section would mislead.
How fresh: Built each night. A group that stops sharing, or moves to another district, leaves the totals above it at the next build, within 24 hours.
young_people_count
Young people. Young people with an active membership, each counted once, however many groups they belong to.
- Counts each young person, not archived, with at least one active membership in the group or node or in any group below it that shares data with it.
- A young person in two groups counts once, so a total above those groups can be lower than the sum of their own
young_people_count. Never addvalueorownValueacross rows to get a total: read the node’s own row. - Counted directly each night, not added up from the rows below, so it is never stale.
unassigned. A young person counts once in each age group they are in, so a child who is a Cub in one group and a Scout in another counts in both rows but once in all. The section rows can add up to more than all.
How fresh: Built each night. A group that stops sharing, or moves to another district, leaves the totals above it at the next build, within 24 hours.
